Benitec keeps BB-301 pivotal trial enrollment planned for mid-2027 after FDA feedback

Benitec Biopharma received FDA Type C meeting feedback seeking more information to support the design of its BB-301 pivotal study in Oculopharyngeal Muscular Dystrophy-related dysphagia. The company said the agency will review the added submission so that the final study plan can be set in Q1 2027, while patient enrollment remains targeted for mid-2027. Benitec also plans to disclose updated early-stage BB-301 results at a gene-therapy meeting in Hamburg in October.

The FDA request makes additional natural-history and other supporting data a prerequisite to locking the pivotal-study design. Benitec says the review timetable still supports enrollment beginning in mid-2027, making the upcoming clinical update and Q1 2027 design decision key milestones.
